I am trying to use the F12 Internet debugging Tool that comes with - yes, Internet Explorer 9. Don't ask...
When I click on the Scripts tab, there is a drop down of javascript files that have been downloaded. to set a break point in one of my script files, I click the drop down and select the JS file. Normally, this list isn't that long, but I've been seeing 100's of scripts that have names such as "poll?transport=longpolling&..@#$@#$@#&@#$@#" and I have to scroll throough this very, very long list until I find my JS file.
What are all these files and is there a better way to locate the JS script I want to debug?
This looks like a SignalR connection. Most likely it's the Browser Link feature from Visual Studio - I believe that uses SignalR internally.
You can disable it from the dropdown next to Visual Studio's refresh icon:
